Glycols & Polyols Available — Bulk Only

Polypropylene Glycol (PPG-26)

CAS 25322-69-4 · Formula (C3H6O)n

A medium-chain polyether polyol delivering surfactancy, lubricity, and defoaming across industrial and personal-care formulations. Polypropylene glycols serve as nonionic surfactants and wetting agents, lubricant and functional-fluid base fluids, defoamers, and intermediates in polyurethane manufacture.

Full Description

Polypropylene glycol (CAS 25322-69-4) is a polyether polyol built from propylene oxide; the PPG-26 grade denotes an average of roughly 26 oxypropylene units. Polypropylene glycols serve as nonionic surfactants and wetting agents, lubricant and functional-fluid base fluids, defoamers, and intermediates in polyurethane manufacture.

Frequently Asked Questions

What is PPG-26?

PPG-26 is a polypropylene glycol (CAS 25322-69-4), a polyether polyol built from propylene oxide; the PPG-26 designation denotes an average of roughly 26 oxypropylene units. It is used as a nonionic surfactant/wetting agent, a lubricant and functional-fluid base fluid, a defoamer, a polyurethane intermediate, and a solvent/conditioning agent in personal care.

Is PPG-26 the same as propylene glycol?

No. Propylene glycol is the small two-carbon diol monomer, whereas PPG-26 is a polypropylene glycol polymer of approximately 26 propylene-oxide units with much higher molecular weight and different properties. They are distinct materials with distinct CAS numbers.

What is PPG-26 used for industrially?

Beyond personal care, polypropylene glycols like PPG-26 serve as nonionic wetting agents and surfactant intermediates, polyether base fluids for lubricants and functional fluids, antifoam agents in process streams, and polyether-polyol intermediates in polyurethane manufacture.

What is the CAS number and HS code for PPG-26?

PPG-26 carries CAS 25322-69-4 (the generic polypropylene glycol CAS) and classifies under HS 3907.20 (polyethers in primary forms). We provide the HS code along with the CoA and SDS to support customs documentation.

What packaging is available for bulk supply?

We supply PPG-26 to manufacturers in industrial packaging including drums, IBCs, and totes, with a CoA and SDS per lot. Request a quote with your target volume and grade for current bulk pricing.
